CARL BRENDEL, OF TSCHUPAUKOWKA, RUSSIA.

SPECIFICATION forming part of Letters Patent No. 769,466, dated September 6, 1904,

Application filell April 6, 1903. Serial N0. 151,302. lNO modelfi To a, whom it 7mm mun/W71..-

Be it known that l, CARL BRENDEL, Ph. Dr. factory director, a subject of the German Emperor, residing at Tschupackowka, in the Empire of Russia, have invented certain new and useful Improvements in Apparatus for the Prevention of Seasickness, of which the following is a specification.

The object of the present invention is to provide means for the prevention of seasickness, which consists in making the long movements of the ship when pitching, rolling, heaving, and setting less felt by the passenger by providing chairs, couches, or a whole platform, forming a part of the deck, and carrying said chairs or couches and giving them either by machinery or by the hand short up and down motions. In consequence of the long movements of the ship being thus changed into a great number of short motions which are constantly interrupted by short movements in an opposite direction the causes producing seasickness are counteracted. The devices for producing the shaking motions may vary.

In the accompanying drawings a few forms of devices are illustrated which serve for the intended purpose.

Figure 1 gives a view of chairs the seats of which are provided with shaking devices. Fig. 2 shows a platform with chairs, the shaking motion being here given to the platform itself. Fig. 3 shows a couch for receiving the shaking motion by the hand.

Similar letters refer to similar parts throughout the several views.

In Fig. 1 the chairs a are provided with elastic seats 6. From the seats cords, wires, or wire ropes 0 pass through openings (Z in the deck (2 over pulleys 7", arranged below the deck, to a bar 9, lying crosswise, to the seats of the chairs, and to which bar the ropes are fastened. This bar receives a to-and-fro motion in the direction of the arrows and causes, through an alternate pulling at and releasing of the rope 0, a shaking of the seats I). For a row of chairs standing side by side a long bar can of course be provided between the legs of the chairs, and to this bar a shaking eccentric S.

motion, as just described, be given, or a motion in a vertical plane, which is then comi municated to the chairs. The shaking motion can also be produced by vertical bars connected to the seats and raised at short intervals by a rotating shaft S, with a cam or an An arrangement of this kind is shown in 2. Here the chairs are standing on two platforms It '1', which, being supported at l, are movable at their ends I in a vertical direction. The shaking motion is communicated to the platform i/t through a vertical bar 111, which is moved up and down in its longitudinal direction by suitable means, as described, and which is provided on the side of the other platform with a curved piece 11, with which it presses from above upon a lever 79, supported at 0. The other end of the lever stands in communication with the platform 1: through a bar g, with turning joints at either end. On moving the bar on up and down not only the platform 11, but also the platform 1', is moved up and down.

Instead of the bar 1/) and the lever q a long plate may of course be made use of in order to give a shaking motion at one and the same time to broader platforms 71 v', with several chairs, unless it should be more advantageous to use several bars 112 or levers q for such pur pose. This can in all cases be arranged to suit the requirements and circumstances. Finally, the shaking motion can also be produced by the hand by pulling at or pressing on handles arranged above the chairs or couches a, which latter are resting on springs, as shown in Fig. 3. For the convenience of travelers arm-chairs or inclined chairs as used on board ship may be substituted for the chairs shown in the drawings. It can also be arranged that on the downward motion of the ship the upward shakes are quicker than the downward ones and, further, that at the rising of the ship the contrary takes place in order to more effectively counteract the main or long movements of the ship.

\V hat I claim as my invention, and desire to secure by Letters Patent of the United States, is

1. An apparatus for the prevention of seasickness, consisting of reclinatory means for the passenger arranged on board a ship, and means connected with said reclinatory means movements of the ship When rolling, heaving and setting, for making said movements of the ship less felt by the passenger on said reclinatory means, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing Witnesses.
